What Ingredients You Will Need

This recipe uses everyday ingredients to create extraordinary results. Here’s what you’ll need:

• Unsalted butter: Softened to room temperature for easy mixing.
• Granulated sugar: Adds sweetness and helps create those slightly crisp edges.
• Brown sugar: For a hint of molasses and extra chewiness.
• Large egg: Provides structure and richness.
• Vanilla extract: Adds depth and enhances the chocolatey flavor.
• All-purpose flour: The base of the cookie dough. For gluten-free, substitute with almond flour.
• Cocoa powder: Use unsweetened for a rich chocolate flavor.
• Baking powder: Ensures the cookies rise properly.
• Salt: Balances the sweetness and enhances the overall flavor.
• Chocolate chips: Semi-sweet or dark chocolate chips work best for pockets of melty goodness.
• Mini marshmallows: For gooey, stretchy perfection once baked.
• Chopped almonds or walnuts: Adds crunch and a nutty flavor (or leave them out for nut-free cookies).

If you want to experiment, you can swap the nuts for pecans or even add a handful of shredded coconut for a tropical twist. For a vegan version, use plant-based butter and marshmallows, and opt for flaxseed as an egg replacement.

Equipment Needed

• Mixing bowls: One for wet ingredients and another for dry ingredients.
• Hand mixer or stand mixer: Makes creaming the butter and sugar a breeze.
• Wooden spoon or spatula: Handy for folding in the chocolate chips, marshmallows, and nuts.
• Baking sheets: Line them with parchment paper for easy cleanup.
• Measuring cups and spoons: Accurate measurements are key to perfect cookies.
• Cookie scoop: Optional, but it ensures evenly sized cookies.

No cookie scoop? No problem! A tablespoon works just as well. If you don’t have parchment paper, a lightly greased baking sheet will do the trick.

Preparation Method

1. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. In a large mixing bowl, cream together ½ cup (115g) unsalted butter, ¾ cup (150g) granulated sugar, and ¼ cup (50g) brown sugar until light and fluffy. This should take about 2–3 minutes.
3. Add 1 large egg and 1 teaspoon vanilla extract. Mix until fully incorporated.
4. In a separate bowl, whisk together 1 cup (125g) all-purpose flour, ⅓ cup (30g) unsweetened cocoa powder, ½ teaspoon baking powder, and ¼ teaspoon salt.
5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until a dough forms. Avoid overmixing—it’s okay if there are a few streaks of flour left.
6. Fold in ½ cup (90g) chocolate chips, 1 cup (50g) mini marshmallows, and ½ cup (60g) chopped almonds or walnuts. The dough will be slightly sticky.
7. Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, spacing them about 2 inches apart.
8. Bake for 10–12 minutes, or until the edges are set but the centers look slightly underbaked. Trust me, they’ll firm up as they cool.
9. Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack. This step is crucial for the marshmallows to set properly.

Pro tip: If the marshmallows start to ooze out during baking, gently press them back into the cookies while they’re still warm.

Cooking Tips & Techniques

• Don’t overmix: Overmixing the dough can lead to tougher cookies. Mix until just combined.
• Chill the dough: If your kitchen is warm, pop the dough in the fridge for 15 minutes before scooping. This helps prevent spreading.
• Use fresh marshmallows: Stale marshmallows won’t melt as nicely.
• Watch the bake time: These cookies are best slightly underbaked for that gooey center. Keep an eye on them after 10 minutes.
• Customize the mix-ins: Get creative! Try white chocolate chips, dried cherries, or crushed pretzels for a fun twist.

These tips will ensure your cookies turn out perfect every time—soft, chewy, and full of flavor!

Variations & Adaptations

• Gluten-Free: Swap the all-purpose flour for a gluten-free baking blend.
• Nut-Free: Omit the nuts entirely or replace them with sunflower seeds or crushed pretzels.
• Vegan-Friendly: Use plant-based butter, an egg substitute (like flaxseed meal), and vegan marshmallows and chocolate chips.

Seasonal twist? Add crushed candy canes for a holiday vibe, or swap the marshmallows for fresh berries in summer. I once added a dash of cinnamon and cayenne for a spicy Mexican chocolate version—it was amazing!

Serving & Storage Suggestions

These cookies are best served warm, when the marshmallows are gooey and the chocolate is melty. Pair them with a cold glass of milk or a steaming mug of hot cocoa for ultimate comfort.

To store, let the cookies cool completely and place them in an airtight container. They’ll stay fresh at room temperature for up to 5 days. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer bag. Reheat in the microwave for 10–15 seconds to enjoy warm cookies anytime!

FAQs

What’s the best way to prevent cookies from spreading?

Chill the dough for 15–20 minutes before baking, especially if your kitchen is warm.

Can I freeze the cookie dough?

Absolutely! Scoop the dough into balls, freeze on a baking sheet, and transfer to a freezer bag. Bake directly from frozen, adding 1–2 extra minutes to the bake time.

What nuts work best in this recipe?

Almonds and walnuts are classic choices, but pecans or macadamia nuts work wonderfully too.
